The head of the European Union's public health agency Andrea Ammon said on Wednesday that COVID-19 vaccine boosters should be considered for all adults, with priority for those above 40 years, in a major change to the agency's guidance.
Recommendations issued by the European Centre for Disease Prevention and Control (ECDC) are not binding on EU governments but are used to make health policy decisions.
"Booster doses should be considered for all adult individuals prioritizing persons above 40 years of age," Ammon said in a recorded statement, noting that boosters should be administered at least six months after completing the primary vaccine schedule.
